Abstract

1,200,588. Controlling variable pitch steering propellers. KARLSTADS MEKANISKA WERKSTAD A.B. 2 May, 1969 [3 May, 1968], No. 22410/69. Heading B7V. A system for controlling the pitch of a steering propeller, e.g. located in a tunnel athwart the hull of a ship, according to the load on the motor 9 driving the propeller, comprises a manuallyactuated "reference value" electrical signal transmitter 25, which is set to the required steering effect, and transmits a signal to a control device 29 incorporating a polarized relay, a load-sensing device 33 on motor 9 transmitting an "actual value" signal, indicating the load on motor 9, to control device 29, and the control device 29 comparing the two signals and actuating a solenoid valve 17 controlling the hydraulic actuator 13, 15 of propeller 1 to set the propeller pitch. Overloading of motor 9, e.g. due to ice in the propeller tunnel, produces a signal from device 33 larger than the signal from transmitter 25, causing control device 29 to reduce the pitch. A device 35 senses the pitch setting of the propeller and controls device 29 to set the propeller at zero pitch when motor 9 stops. Motor 9 may be an asynchronous A.C. electric motor, and device 33 a current transformer in the supply line 31 to the motor. Alternatively, the motor may be D.C. electric or a diesel engine.
